Button



WVILLIAM J. LEOKIE, 2]), OF BOSTON, MASSACHUSETTS.

BUTTON.

SPECIFICATION forming part of Letters Patent No. 412,961, dated October 15, 1889.

Application filed March 27,1889- To all whom it may concern:

Be it known that 1, WILLIAM J. LEOKIE, 2d, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Buttons, of which the following is a full, clear, and exact description.

My invention relates to that class of buttons adapted to be clamped or locked to the fabric, and has for its object to so improve the construction of the button for which Letters Patent were granted to myself February 7, 1888, No. 377,625, that the cost of manufacture will be materially lessened, likewise the number of parts, and a more effective grip be obtained upon the fabric.

The invention consists in a button comprising a body provided with a shank, a flange secured to the said shank, and spurs proj eoted from the said flange, and in the specific construction of the button, as will be hereinafter more fully set forth, and pointed out in the claim.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters and figures of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the button and fastening device. Fig. 2 is a bottom plan view of the same; and Fig. 3 is a central vertical section through the button and fastening device, illustrating the button as applied to the fabric.

The button is formed with a body 10,which may be of any design or contour, provided upon the under face with a shank 11, said shank being reduced, as illustrated at a in Fig. 3, whereby a shoulder 12 is obtained. A sleeve 13 is shrunk or otherwise rigidly secured upon the shank between the body 10 and the shoulder 12, which sleeve, preferably Serial No. 305,009. (No model.)

extending down to the said shoulder, is pro vided at that point with a horizontally-disposed flange 13. From the periphery of the flange a series of spurs 14 are downwardly projected, essentially at a right angle, as best shown in Figs. 1 and 3. The reduced portion of the shank is threaded.

As a means of locking the button upon the fabric A, a nut 15 is screwed upon the threaded end of the shank, which not is preferably constructed as illustrated, being provided with a series of wings 16, and having the upper face slightly carried above said wings, as shown at 17 in Figs. 1 and 3. The nut may be provided with as many wings as desired. In operation a suitable aperture is made in the fabric, and the threaded end of the shank is passed through the said aperture until the spurs 14: have entered the fabric a suitable distance. The nut 15 is then screwed upon the threaded extremity of the shank to a bearing against the fabric, whereby the said fabric is held in contact with the spurs.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- As-an improved article of manufacture, a button comprising a head 10, an integral shank 11, reduced at its outer end and externally screw-threaded, a sleeve 13, secured on the said shank above the screw-threaded part thereof, resting against the under side of the head, and having an outward projecting flange 13 in line with shoulder 12, and provided with peripheral teeth 14, extending toward the threaded end of the shank, and a thumb-nut 15 on the threaded end of the shank, substantially as set forth.
